st: Need Help with Clusters and Weighting

Hello Stata Users List,
I'm working on my dissertation and need to analyze a small dataset (n=210) by logistic regression (with odds ratios). I have nine variables (all categorical or binomial) and my outcomes are binary Y/N. Data was obtained conducting a survey from 7 samples in each of 30 clusters. The clusters were soft-stratified in 3 groups according to income levels, as low, medium and high. I want to be sure than my sample is representative of the population in Harris County, Texas.
Should I weight for the clustering to analyze within a stratum? If yes, what are the commands?
What are the commands to do weighting for the strata, and the clustering, when analyzing over the entire sample?
Do I use income levels, crude income, or the population in each cluster as the weight?
Thanks.... I still have a lot to learn.
